Abstract

See full text

A supersaturated solid solution soft magnetic material and a preparation method thereof are provided, belonging to the field of metal soft magnetic technologies. The supersaturated solid solution soft magnetic material is soft magnetic alloy with proportions of 72.0˜78.0 at % Fe, 12.0˜18.0 at % Si, 4.0˜12.0 at % Co and 1.0˜3.0 at % Ti. The preparation method uses molten glass purification or electromagnetic levitation melting to an alloy melt with a target supercooling degree, increases the solid solubility of the Ti element in α-Fe (Si, Co), and promotes the formation of supersaturated solid solution of Ti, thereby achieving the goal that the magnetocrystalline anisotropy constant and the magnetostriction coefficient tend to be zero. Ti element is uniformly distributed in the α-Fe (Si, Co) after supercooled solidification analyzed by X-ray energy spectrometer, a supersaturated solid solution alloy without Ti precipitation is obtained, and the soft magnetic alloy has low coercivity and high permeability.
